Robots compete by following a winding line on a series of tiles to a designated rescue area. On the way the robot could encounter obstacles, bridges and short cut opportunities that will challenge the most intrepid programmer. After negotiating the randomly selected path, the robot arrives at a green coloured area which indicates a chemical spill they need to find "the victim" and control it (contain or lift) and then manoeuvre it out of the chemical spill. Finally they need to save the robot and exit the chemical spill from where they entered.
